Handle < and > in array column specifiers #166
Description
I just discovered the next issue when array's is used instead of case.
The test case:
\documentclass{scrartcl}
\usepackage{amsmath}
\usepackage{array}
\begin{document}
\setlength{\arraycolsep}{1pt}
\begin{equation}
x =
\left\{ \begin{array}{>{\arraybackslash$} p{3cm} <{$} l}
y - 1, & \mbox{if } 1 \\
y, & \mbox{if } 2 \\
\end{array} \right.
\end{equation}
\end{document}
Error:
[WARNING] Could not convert TeX math 'x =
\left\{ \begin{array}{>{\arraybackslash$} p{3cm} <{$} l}
y - 1, & \mbox{if } 1 \\
y, & \mbox{if } 2 \\
\end{array} \right.', rendering as TeX:
ft\{ \begin{array}{>{\arraybackslash$} p
^
unexpected ">"
expecting white space, letter, "|" or "}"

What is the meaning of the column specifiers
{>{\arraybackslash$}and<{$}?That's the part the parser doesn't seem to understand.
